I started to learn more about this game, but some things are not clear for me, maybe someone could help me.

The ace could b e count as 11 or 1, we know, the palyer can choise. But can the dealer too? Example the dealer first card is 6, than ace. Its for he counting as 17 or 7? Or He get A, then 4, then again A. These cards how to count? 11+4+11 OR 11+4+1 OR THIS IS DEALER DECISION?
